That isn't an official communication from Mozilla. That is "someone's" recollection of something "someone" said (or not) at some workshop:
"Fair warning: I don't speak for Mozilla. Everything I say here is a recording of my memories from that event. Nothing more. Nothing less."
(and yes, I noticed that the second "someone" is Mozilla's "Add-ons Policy Policer, Thunderbird Council Chair", but my point still stands: this is something "someone" said, not Mozilla's official position)
